I This invention relates to improvements in -pails or Vcontainers into Which milking is done, and the essential objects are vmainte- Y nance of "eifective sanitary conditions and preservation against Waste. v

In greatendetaika further object is the limitationlof thefreceiverlportion of a receptacle to such relation to other parts of the receptacle as Vto limit the use, of there- Vceptacle to those conditions assuring freedom from Spraying of milk or other loss thereof during the milking operation, and at the same time assuring preservation of maximum cleanliness.

With these and other objects in View Aas Will'in part hereinafter become apparent and -in'y part be stated,'the invention comprises a container and a receiver therefor located .Y Withrespectto the container in such relation as to induce properdischa'rge of the loss and to insure maximum'sanitation. l

V.The invention also includes a guide for incoming streams of vmilk for directing the samefwitho'ut sprayl or other loss through a bacteria-"carrier remover on the Way to the `ir'lterior of the receptacle.

. YThe invention-also includes Va receptacle shaped and'formed to avoid provision of' 'lodgment `places for bacteria and bacteria carriers,fand in combination therewith means for delivering milkto such container in a high state of sanitation.`

The invention'also comprises certain other Vnovelv constructions,- combinations, and ar- '.rangements of parts as subsequently specified and claimed. n Y

In the .art of milk .pa-il construction, many .forms vhave been proposed in an attempt to improve the process v.of 'milking both Afrom the "standpoint of `cleanliness andV :preservation ofthe product. A popular form has lof the structure seen in Figure includingthe j .included afunnel-like opening terminating l in a strainer so located'that all milk passng into the receptacle must pass through the strainer, but dificulty Yhas been expe# `Vrienced 'even With such devices, because impact of the streams of milk invariably results Vin theproduction of spray and the formation of foam. Loss is occasioned by the spray falling outside of the receptacle intake, and

kantunsanitary condition :is liable to occur When bacterial carriers .lodge fon or in the foam. Also,-difliculty has been experienced ineffective cleansing of receptacles after use-'incident to the presence of seams and other ledges on or in which jlodgment is afforded.

The present inventioneliminates all ,opportunity for lodgmentand aords incentive to so direct the milk streams as tor'entirely'avoid spraying and largely-,reduce foam formation.

`Vindicates the. body of `a container which is Vpreferably substantially' cylindricalv and 30 material-ofthe :Wall lfand lits integralcover 5 is of sheet material, and preferal! ly of sufficiently highly ductile metal to be drawn from a single integral piece, and the opening 4 1s formed by providing a finished'margin of said walls bordered by a roll or like stiening bead 6 formed of the material of the wall. The openingy 4 is preferably ovate with its majorY axis vextending across the frontV portion of the receptacle and its minor axis extending substantially from the eXtreme foremost portion of the vertical wall`1 rearward toA aboutY the middle ofthe container'.

In some forms, as will be hereinafter morev specifically pointed out, a spout or 4pouring orifice will not be required, butin such forms c or embodiments -as are supplied with such :pouring orifice, -.the .same is preferably arranged at the opposite side ofthe cover orrtop '5,from the opening 4, the spout 7 being preferablyformed integral withthewall 1 and ,top 5,l and being preferably sufficiently short Ato. lie .substantially within the extended lines ofthe sidewalls 1. v,An appropriate, removable 'cap V.8 .is-applied to .the spout 7 and re# Ytainedfrictionally in place during' all use of ithe receptacle 'exceptwhen' milk isbeing vpoured therefrom. f i Y 1 Y snugly. fitting within andclosing the opening 4 isa chute'9, which chutefconsists of an inwardly and downwardly converging tubu-Y lar body .whose outer endis iiared tov an oval contour proportioned tosnugly and frie- Vti'onally fit Within thebead 6. The 'chute 9 :at its upper or Vouter end is preferably flanged, at 10, to overhang the bead 6 and provide a Apositive supportas wellas the frictional support offered by' engagement with the bead. An outstanding lip 11 is preferably Vprovided at one place on flange 10 for facilitating manualy removal of the chute -9'from engagement with the bead 6.v The chute :9 is Vinclined rearwardly from the opening'4 andvis `eX- tended until the lower or innerend of the chute lines almost. wholly vbeneath the cover 5, andmay be arranged to completelyl under- ,lie the cover. The 'lower end Vportion lof the chute 9'. is .preferably turned abruptly Vfrom the direction of the chute tov provide a substantially straight pendent mouth or intake opening bordered by a iiange 13. Vflange 113 is preferably formed at its lower extremity .with an annular recess forming an outstanding bead14. and immediately above the kbead 14 the vmaterial is formed into anannular depression 15 providing a second bead con. 'strict-ing the opening. @A frictionring or 'band 16 is adapted'to engage the bead 14A with sufficient friction grip to retain the band Yin place when notY in use;A When in use, va

strainer is provided consisting preferably' of fabric and fiber arranged-in theffor'm of a vsheet andy stretched across the intake openl ing surrounded by flange 413, thesaid fabric extending across the-lower edgeofthe lflange and being clamped into place by the frictional groove 15 allows a certain amount of eXpansion or lateral displacement of the fabric material so that the effectivel gripping action is substantiallyalongthe line corresponding with the crown. of the bead 14. The filtering fabric may assumepany of various embodiments, butv preferably consists of spaced layers of gauze "with interposed layers of cotton fiber or like effective filtering material.

Aforaminous platel'? is arranged within the'opening surrounded by flange 13 and proportioned to Vrest on the bead `produced by groove 15. The openingsurrounded by flange 18 maybe of any preferred cross` sectional ',contour, but is preferably circular, and the foraminous plate 17 corresponds in shape.

The `chute 9 ispof, such shape and location that ordinarily the plate 17 when removed can be effectively A,replaced upon its seat by merely being dropped into'the chute along which it will slide by gravity until it settles on itsV seat. The plate 17 Vwhile foraminous 21nd, therefore, capable of restricting passage of large objects, is not essentially intended as fa vscreenor filter but serves chiefly to take the impact of the incoming streams of milk, so

that vtheir Vforce will not be exerted on Vthe filtering fabric beneath. c To facilitate manual handling,kan.appro priate bail 18 vis providedand engages ears A1,9, 19flxed to thesides of the receptacle preferably in position to vextend across the fre'ce'ptacle approximately parallel,l to the major axis of' opening 4. Other means'of convenient' handling of the r'eceptacleinay be providedas desired.4 l In operation, the pail ris located with the opening 4 presented vtoward the'udder, and thel milkerfdirects the streams of milkinto the chute 19. The natural tendency ofthe 'operator will be to cause the streamsv to iiow on inclined lines substantially paralleling the -Walls of the chute, so that the streams strike the plate 17 and are occasioned noop` 'portunity `for spraying or other loss. Should any slight spraying occur, the upper wall of theV chute 9 is so located as to receive the impact and cause the stray material to collect and be returned by gravity.l v Y 1 f lVhen the milking has been completed and the receptacle is tobe emptied, the milk may be Ypoured through thespout 7, or, if preferred, the lip 11 may bel engagedand the chute 9 lifted suiiicientlv for allowing the milk to ibe poured from'the receptacleout beneath thechute. When this latter action is to be regularlypracticed, the embodiment illustrated in Figures and 6 is preferably employed, as will be hereinafter described. l/Vhen the receptacle has been emptied, if

ening in the top, the top and said and a spring clip engaging outer end portion and tennot intended for continued use in the comsloned to maintain frictionalengagement bepletion of a milking operation, it must be cleansed, and, in that event the chute 9 is completely removed by being Withdrawn longitudinally through the opening 4, and the operator will find that the unbroken surfaces Within the receptacle effectively lend themselves to a cleansing operation. The chute 9 may be easily and e'ectively cleansed by pulling off the band 16, discardingthe fabric, and removing the plate 17. All parts should be thoroughly cleansed before being reassembled. The plate 17 lits in such a manner that it will readily fall from place upon inversion of the chute 9, and the band 16 beingV only in frictional engagement may be readily forced olf. Fresh fabric, of course.l will be employed with each new operation of milking.

In Figures 5 and .6, I have illustrated a slightly modified embodimentwhich so closely simulates that just described as to be identical with it except for the omission of the discharge spout and the provision of friction means for the intake chute. For that reason, the same reference numerals have been applied and the same description Will be relied upon except for the slight details modified to provide the desired friction. Said details consist of a spring 20 and an enlargement 21 of bead 6 to afford means of frictional engagement by spring20. Spring 20 is in the nature of a clip xed to the upper Wall of the chute 9 and bent to enclose and frictionally engage the enlargement 21 under spring pressure. Spring 20 is but a Astrap spring and may be fixed to chute 9 in any appropriate manner, its free end portion being shaped to cause the spring to frictionally engage and slide upon the enlargement 21 When the chute 9 is elevated to the position Seen in full lines in Figure 5, Wliereat the directly from the re- Y milk may be poured ceptacle beneath the chute. When the pouring operation has been completed, the chute is pressed back to the dotted line position of Figure 5 Where it again closes the opening 4, and the spring 20 exerts a pressure tending to retain the chute in the last-named position. Spring 20 functions to retain the chute in any given position, and is suiiiciently elastic to allow the chute to be bodily Withdrawn when suilicient pressure is exerted to cause the spring 2O to free itself from the extension 21.

What is claimed is In a milk pail, the combination, with a container having a top partially closed, of an intake chute extending completing the closure thereof, the said chute being turned at its outer end portion to `an Y angular. relation to the main body of the chute and proportioned to snugly iit the opthrough the ytop and tween said outer end portion and the top.
